Estimation of waterfall height in the downstream of ogee spillways to hydraulic jump control

مدل‌سازی و مدیریت آب و خاک, 2021
IntroductionThe purpose of this study is to generate the relationships to directly calculate waterfall height at the downstream of the spillway to form a jump at the toe of the spillway and to prevent erosion and destruction of the downstream river bed or body of the spillway in a submerged and free hydraulic jump.

Evaluation of scale effects in physical modeling of combined ogee and sharp-crested weir flow using a 3D CFD model

Water Science and Engineering
Research on scale effects on flows over weirs has been conducted on a limited basis, primarily focusing on flows upstream of a single-type weir, such as ogee, broad-crested, and sharp-crested (linear and non-linear) weirs.

Pengaruh Variasi Jari-Jari Kolam Olak Tipe Trajectory Bucket terhadap Loncatan Hidrolis dan Peredaman Energi pada Spillway Tipe Ogee [PDF]

, 2016
The need for water is not always matched by the availability of water, both in space and time. One man’s attempt to take advantage of the water so it can be streamed on the places that need water (irrigation water) is the making of the dam (weir). In the
